Title:
METHOD AND DEVICE FOR PERFORMING CHANNEL CODING ON BASIS OF POLAR CODING IN WIRELESS COMMUNICATION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2020/045943
Kind Code:
A1
Abstract:
A method for transmitting signals using polar coding to a second device by means of a first device according to the present disclosure may include: a step for encoding a first bit sequence of length K which includes a first information block, a second information block, a first cyclic redundancy check (CRC) for the first information block, and a second CRC for the second information block, on the basis of a polar code of size N; a step for transmitting a first signal on the basis of the encoded first bit sequence; a step for receiving first hybrid automatic repeat request acknowledgement/negative-acknowledgement (HARQ ACK/NACK) information for the first bit sequence; a step for dividing the second information block into a first sub information block and a second sub information block and generating a third CRC for the first sub information block, on the basis of the first HARQ ACK/NACK information including information indicating failure of the transmission of the second information block; a step for encoding a second bit sequence of length L including the third CRC, on the basis of the polar code; and a step for transmitting a second signal on the basis of the encoded second bit sequence.
